Sodium, Potassium and zinc have all been promising contenders for lithium’s place in rechargeable batteries of the future, but researchers have added an unusual and more abundant competitor to the mix: chloride, the richest negatively charged ions in seawater. Xiaowei Teng, the James H. Manning professor of Chemical Engineering at WPI, has discovered a new redox chemistry empowered by chloride ions for the development of seawater green batteries.
